The Bodleian Library has 2 versions of this. I also found it in The Goldfinch (J. Gold, 1805), page 98.

YOUNG WILLIAM WAS A SEAMAN TRUE

Young William was a seaman true,
The darling of the bonny crew,
For blithe he was and kind;
For tho' no lagging lubber he,
Right loth he was to go to sea,
For Jane he left behind.

And Jenny lov'd, but all by stealth;
Her father had much store of wealth;
Of Will he would not hear;
Till cruel chance at length reveal'd
The passion they so long conceal'd,
And William lost His dear.

A friendly voice poor William hail'd;
A ruffian gang the youth assail'd,
'Twas done by cursed gold;
The tender for the offing stood,
The cutter skimm'd the yielding flood,
They hatch him in the hold.

She, troubl'd, walks the beach in haste,
And troubl'd look'd the wat'ry waste;
And by the floating wave
A corpse was wash'd upon the shore;
'Twas William! and with tears they bore
Two lovers to the grave.
